Q2: List common types of technical documents used in NDT
A2: Standards, procedures, specifications, codes, techniques, instructions, and reports.
Q3: What are the three key obligations of an inspector?
A3:
1. Understand the part being inspected (dimensions, service use).
2. Perform inspection per standard practice.
3. Know the governing code or specification.
Q4: Define a standard.

Q5: Name the two most common ASTM standards used for magnetic particle testing.
A5: ASTM E709 (Guide for Magnetic Particle Examination) and ASTM E1444 (Practice for Magnetic Particle Examination).
Q6: What information is typically found in an NDT standard?
A6: Scope, reference documents, method description, general and specific practices, quality control, and mandatory/non-mandatory information.
Q7: Define a specification.
A7: A detailed statement of requirements for a material, product, or process, including workmanship and acceptance criteria.
Q8: What is the main purpose of a specification?
A8: To set minimum acceptance criteria and define acceptable or rejectable discontinuities.
Q9: What is a code?
A9: A set of legal rules or standards governing construction and inspection, established by a regulatory body, carrying enforcement authority.
Q10: When does a specification become a code?
A10: When it is required and enforced by a legal or regulatory authority.
Q11: What is the difference between standards/procedures and specifications/codes?
A11: Standards and procedures tell you how to perform an inspection; specifications and codes tell you what to do with the results.
Q12: List typical contents of a code or specification
A12: Procedure, personnel qualifications, accept/reject criteria, and reporting requirements.
Q13: What factors differentiate discontinuities from defects?
A13: Type of discontinuity, size, location, effect on service life, and consequence of failure.
Q14: What is one of the key roles of an inspector regarding discontinuities?
A14: To evaluate discontinuities using applicable codes or specifications to determine acceptability.
Q15: What is the purpose of written procedures?
A15: To outline step-by-step methods for inspecting a particular part, material type, or situation.
Q16: What elements must a written procedure include?
A16: Description/scope, personnel qualifications, equipment, safety precautions, preparation, evaluation/reporting steps, and post-inspection activities.
Q17: Describe a written technique.
A17: A document more specific than a procedure, created for known equipment and particular parts, often including setup details and previous results.
Q18: What is a written instruction?
A18: A detailed document written by a Level II to guide a Level I inspector on exactly how to perform an inspection on a specific part.
